Pop-up error window in an infinite loop on click of button



When user clicks on the button to attach a file to Data-WorkAttach-File class the pop-up window opens.
And this pop-up window does not close and gets continuosly displayed. 
Note: This issue is seen earlier as well,  but with IE 11 compatibility view setting and disabling the script debugger it works fine. But now it occurs continously even after applying these configuration setting.
The workaround is to close the work object and reopen it again.
This is seen after installation of some of the hot fixes provided by Pega in recent days.
